It just creeps up on you, you don't really feel it at all, just that performance is improved, but you wouldn't ever know. (in my experience) it's only when you stop it that you notice the difference. One thing I do notice the difference with though is recovery - I play 5s on a monday night, it's always fast, hard, 60 minutes of sprints and a few brutal tackles :) and when I am taking creatine my recovery is much better and I'm not as stiff or sore the next day.
